- TRUCK SIDE FRAME.

Specification of Letters Patent. I P te t e 10, 1920.

Application filed August 9,1917. Serial No. 185,243.

' therefor.

One of the objects of the invention is to simplify, lessen the cost of, and at the same time strengthen side frames of car trucks.

Another object is to increase the resistance of the yoke portion of side frames against transverse strains set up in starting andstopping cars.

Another Object is to provide a novel truck side frame adapted to meet the various requirements for successful commercial operation.

These and other objects are accomplished by providing a truck side frame having in combination spaced tension and compression members, a yoke extending therebetween, and a reinforcing member connected to said yoke and to the compression member.

The invention is illustrated on the accompanying sheet of drawings in which,

Figure 1 is a side elevation, parts being in section, of a truck side frame embodying my invention;

Fig. 2 is a top plan view of the same;

Fig. 3 is a transverse sectional view taken in the plane of line 33 of Fig. 1, and

Fig. 4t is a sectional View of the yoke member and cooperating reinforcing member taken in the plane of line 4% of'Fig. 1. The various novel features of my invention will be apparent from the following if description and drawings and will be particularly pointed out in the appended claims.

Referring to the figures of the drawings, it will be noted that I have provided a truck side frame having a compression member 10 and tension member 11, the same being spaced from each other at their middle portions and having interposed therebetween a central yoke 12. In this particular case the compression member includes two angle bars 13 and 1 4, the middle portions of which are horizontal and slightly raised, said bars then extending laterally and downwardly c011- vergmg toward the outer ends of the tension -member'll to which they are secured. The tenslon member 11 in this case is preferably of channel section with its flanges extending upwardly toward the compression member.

The middle portion of the tension member 11 is curved and its lateral portions extend upwardly and outwardly to points of con nection with the compression member.

The yoke 12 which is interposed between the tension and compression members, is preferably of plate material and is rolled into a .U-section and the yoke is also in the form of a U. The bottom portion of the yoke 12 rests in the central channel portion of the tension member 11 and is'curved in accordance with the curve in the tension member. The side columns 15 and 16 of the yoke member 12 extend upwardly and pass between the vertical'flanges 17 and 18 of the compression angle bars 13 and14l. The upper ends 80 of these" columns 15 and 16 extend beyond the vertical flanges'l'? and 18 of the compression bars 13 and 1 1 and their opposite walls are bent in opposite directions to hookover the respective flanges 17 and 18 to relieve the rivets 19 of considerablestrain. It will be noted that the rivets 19 passthrough the vertical flanges 17 and 18 of the angle compression bars 13 and 1 1' and also through the upper ends of the side columns of the yoke member 12.

The lateral'walls 20 and 21 of the side columns 15 and 16 extend inwardly toward each other and are arranged to receive'oppositely extending legs 22 of a U-shaped reinforcing member or auxiliary yoke 23 of T- cross-section. The upwardly extending leg 24of the reinforcing member 23 extends betweenthe vertical flai'iges 17 and 18 of the compression bars 13 and 14:, rivets 25 passing throughsaid vertical flanges 17 and 18 and also through the vertical leg portion 24 of reinforcing member 23. Rivets 26 also pass through the lateral walls 20 and 21 and the oppositely extending leg portions 22 of the reinforcing member'23 to securely fasten the reinforcing member 23 to the side columns 1-3 and 16 of the yoke 12. By m eans of se curing the reinforcing ineinber to the side f which greatly reinforces the yoke 12 in re sisting strains set up during starting and stopplng of cars.

It will be appreciated that the opening formed between the side columns 15 and 16 of the yoke-is for the reception of a bolster which normally occupies the upper half of the space between said columns 15 and 16.

and bears against the lateral faces 27 of the reinforcing member 23. In order that the bolster with its associated brackets (which are not shown) may be passed through the opening between the side columns 15, and 16, the lateral walls 20and 21 are rolled oven to increase the space formed in the lower half of-the yoke member. The bolster, as is well appreciated, is held in its normal raised position between the downwardly extending portions of the reinforcing member 23 by a suitable spring or springs, the lower portions of which rest in a sp 'ing seat 28which is received in the lower channel portion of the yoke 12. The tension member 11, yoke 12 and spring seat 28 are connected together by suitable rivets 29.

With this yoke member 12 connected to the tension and compression members as it is, and with its cooperating reinforcing auxiliary yoke member 23 connected there to and to the compression member, a rugged arrangementis provided adapted to meet the various requirements for successful commercial operation.

It is apparent that there may be modifica:

tions of the invention as herein particularly shown and described, and it is my] intention to cover all such modifications which do not involve a departure from the spirit and scope of the invention as set'forth in the following claims.

I claim:

1. A truck side frame including spaced tension and compression members, a yokeextonding therebetween and having one end hooked over said compression member to share the load, and a reinforcing member within and connected to said yoke and to the compression member.

2. A truck side frame including spaced tension "and compression members, a main yoke extending therebetween, and a supplemental reinforcing yoke connectedto said 7 main yoke and to one. of said members.

3. A truck side frame including spaced tension and compression members, a yoke of U-section extending therobetween, and a reinforcing member having flangeswhich are received by U-portions of the side columns of the yoke for reinforcing the yoke.

4. A truck side frame including spaced tension and compression members, a yoke of Usec'tionextending therebetween, and areinforcing member having flanges which are received by U-portionsof the side columns column members hooked over the compression member to share the load, and a reinforcing member between and connected to said column members andto said compression member.

6. A truck side"f1'ame. including spaced tension and compression. members, means extending therebetween comprising column membershaving.flanges and being hooked 'over the compression member, and a reinforcing member between and connected to said column members between said" flanges and connected to said compression member.

7. A truck side frame including a tension member, a compression member includ ing spaced bais, means including column members extending between saidtension and compression members and hooked over the latter, and a reinforcing member between and secured to said column members and having a flange secured between the bars of said compression member. 7

8. A truck side frame including a tension member, a compression member comprising spacedbars, a yoke having column members with flanges and extendingbetween said tension and compression members, and a reinforcing member having flanges secured between the flanges of said column members and having a flange secured between the compression bars. V

A truck side frame includin 1 a tension, member, a compression mem er comprising spaced" bars, ayoke having column members with flanges and extending between said tension and compression members, and a reinforcing member having flanges securedbetween the flanges of said column members and having a flange secured between the compression bars, the upper ends 'of said column members being hooked over said compression bars to share 7 the load. I
